Title: Would This Chinese Jack Be A Suitable Substitute For A Switchcraft One?
Post by: Pollys13a on March 06, 2024, 03:40:10 am
I have a Chinese input jack, see attached photos. I think this is the same as this Switchcraft one.

Cheers.

Yes it is electrical the same , very cheap, but it will work. Will it  last many years ? 

I will never use them, you may have a bad ground issue = noise, hum....

If I was to pick a location on my rig to have a cheap jack, it would be the guitar! 
Come to think of it, not sure I ever bought a guitar that didn't have a cheap jack  :m13

That metal looks awful thin.

Start saving-up for a Good Brand jack for when this one lets you down.

In my experiences, they are not. Jacks are one area I upgrade to get rid of these chinese jacks. I don’t skimp on jacks at all when possible. Especially being a wear item. Jacks, Pots and switches are worth the extra $ unless you’re in a pinch and that’s all you got.

While I have encountered this jack and it "works" I have found shortcomings.
Usually poor mechanical strength and I have seen insulation creep from "one second too long" with the soldering iron.
I have to agree with PRR and Jalmeida, ie spend your money on a quality Jack (which is robust and reliable).

Why not use a stereo jack?  Does it matter?, nope.  Suspecting, that's the jack he has.

Not on a guitar. Read the top post again.

Post is about an amp .

As you know, we can use any king of jack on a guitar; standard jack, schunted type jack or stereo jack.
The two last one are only little more expensive.

Question about jacks, while we're on the subject..

Are stereo (TRS) type jacks used as a mono jack + NO switch in applications like effects boxes, active pickup electronics, etc?

So when you jack-in with a mono (TS) plug, you get both the TS audio circuit and a closed switch contact to ground between R & S thar can power up electronics?

Many effect pedals use a stereo jack on the input. The battery ground connection connects to the "ring" and connects to the sleeve when a mono plug is inserted. The battery is disconnected when no plug is inserted. Saves batteries. Even my 1970 Crybaby uses a stereo jack as a battery saver.

Right, that's exactly the sort of thing I had envisioned. Thanks.
